Wireless TV headphones that operate with Infrared signals have great benefits and and some obvious drawbacks too. Here’s how they work: The transmitter sends an infrared beam of invisible light to the headphones typically in the 2-4 MHz band.
The Infrared signal emitted by a standard household remote or pair of wireless …
